Zurn Z667 – Cast-Iron Trench Drain

The Zurn Z667 is a modular cast-iron trench drain engineered for continuous surface drainage in high-traffic hardscapes—think retail promenades, plazas, loading areas, and parking decks. Rugged construction, interchangeable grates, and project-friendly accessories make it a reliable choice from design through maintenance.

Technical overview: Z667 employs cast-iron channel sections with bolt-down grates, anchoring provisions, and end/outlet options to create long, sloped or level runs. Plain English: it’s a tough, linear drain that catches sheet flow along curbs, facades, and entries—keeping walkways drier and safer.

Key Features

  • Modular cast-iron channels — assemble straight runs with robust impact resistance.
  • Bolt-down grate system — secure, serviceable grates help deter theft and movement.
  • Anchoring/leveling provisions — stabilize sections during pour for clean lines and proper slope.
  • End plates & outlets — options to tie into site drainage (confirm sizes/styles on submittal).
  • Traffic-ready durability — built to handle carts, pedestrians, and light vehicular loads (verify rating per project).

Where Z667 Excels

Choose Z667 for pedestrian plazas, storefront aprons, parking structures, dock aprons, and streetscape edges. Linear capture reduces ponding at thresholds and expansion joints, improving slip resistance and limiting freeze-thaw damage.

Benefits (Plain English)

  • Cleaner hardscapes — intercepts sheet flow before it spreads across walking paths.
  • Faster installs — modular sections, anchor lugs, and field-trim accessories speed layout.
  • Predictable maintenance — bolted grates and open channel profile simplify debris removal.

Specifications at a Glance

System: Cast-iron modular trench drain

Grates: Bolt-down; patterns & openings per spec

Sections: Straight channel modules; end/outlet pieces available

Anchoring: Lugs/fixtures to stabilize during pour

Load Rating: Project-dependent (confirm class/traffic on submittal)

Applications: Plazas, concourses, parking, mixed-use streetscapes

Always confirm grate style/opening, coating/finish, outlet size/type, and load class to match civil and architectural plans.

Installation Highlights

1) Base & Alignment

Prepare a stable base, stringline the run, and set channel elevations to achieve design slope or level grade.

2) Anchor & Pour

Use channel anchor lugs and bracing to resist buoyancy during the concrete pour; verify grate seat is clean.

3) Finish & Commission

Install grates with specified hardware, torque per manufacturer, and confirm outlet connections are watertight.

Case Study: Mixed-Use Plaza Retrofit

A city plaza retrofit replaced spot drains with continuous Z667 runs along storefronts. The modular cast-iron system captured wind-driven rain before it reached entrances, cutting ponding incidents by ~60% during storms. Facility crews praised the bolt-down grates for security and the open channels for quick debris removal after events.

Frequently Asked Questions

Which grate pattern should I specify?
Match opening size and pattern to use case: narrow slots for heel-resistance, larger openings for high debris areas. Confirm ADA/heel-proof criteria where required.
What load class is Z667?
Load capacity depends on the grate selection, embedment, and slab design. Verify the target class (pedestrian, light-vehicular, or higher) on the project submittal.
Can I tie multiple runs to one outlet?
Yes—use end/outlet components and branch piping per the civil drawings. Maintain channel slope and provide cleanouts for long runs.
